thinking now i'm gonna swap the mag coil over to the grubee bottom end when i rebuild it. that way i'll have time to pull this one apart and carefully inspect everything in it.Be sure and check the lower con rod bearing and make sure it is not missing rollers, this is what happend to my first engine that did exactly what you just described yours did.....
Mine seized up on me, I was able to get it unseized and then I thought it might be ok, I put it on another bike an it started and seemed to run fine, I took of one day on a 8 or 9 mile trip and on the way back about 200 yards form my house itjust quit and wizzed down to nothing, I could tell it had lost all compression....so I knew it wasn't a good thing that just happened, I pulled the jug and I had a ring broke, deep score it piston, deep score in cylinder wall, large chunk busted out of transfer port and then after checking things closer I realized that I was missing one or 2 needle bearing on the crank because there was way too much space in between the ones that were left and I could see that they tried to turn at an angle on the crank instead of sitting straight on the crank journal.
This is when I got a used crank form someone and rebuilt that engine and it ran very good until that used crank petered out on me and ate into the case on the clutch side allowing the mag rotor to eat into the case on it's side and destroy the crank seal.
Check that lower end out very good or you may be rebuilding another grenade.......
best wishes to ya
Peace
Very good idea.....I would hate to see you put all that money and trouble in that lower just to hammer it again like I did mine..........thinking now i'm gonna swap the mag coil over to the grubee bottom end when i rebuild it. that way i'll have time to pull this one apart and carefully inspect everything in it.
ouch man, that sucks.Very good idea.....I would hate to see you put all that money and trouble in that lower just to hammer it again like I did mine..........
I was just being a cheap skate noob when I did mine, but I learned a valuable lesson from that mistake.
Yeah, I really should have known better with all the small engine I've built up and repaired over the last 30 years, I wasn't sure what my problem was at the time and thought since the engine came loose I would just go ahead and give it another try...........it lasted about 10 miles and bam ther she went and it was done, that lower con rod bearing was faulty from the factory and it cost me that engine, only thing I saved was the case and clutch parts, then I rebuilt it with a used crankshaft that looked to be in very good shape and it failed again after only 420 miles, engine was still running but the crank shifted and ate up the case under the mag rotor which also destroyed the crank seal which caused it to rev out of control and run like it had cruise control...it didnt run long this way and the jug, piston and rings are all still in good shape, so I'm gonna order a new lower engine assy. from BGF and just put the jug & piston over on it and after a short run in period for the lower end, I should have myself another good engine........if the lower I get is a good one.!ouch man, that sucks.
was almost tempted to get some puch parts to replace it with c:
You would just love our Texas weather then, over 100 here today and thats in the shade.it was so hot out today i had to go for a 8 mile ride to cool off. a woppin 72 degrees felt like i was in an oven
Hey Dan send those skeeter my way and I'll send them back with 3-4 more on them.......we are in the same boat down here where I live, and we haven't had much rain at all.......I just went and bought 5 dozen bass Minnows today and put them in a stock pond thats about 50 yards from my house, I'm hoping they will eat some of those skeeter larva.......LOL WA. I read th 1st 5 words and thought; "wut, got up to 70?"
80 and muggy today here after the snowiest winter I have seen in CT. It just rained for 11 st8 days and we got 'skeeters bitting skeeter as we 2 legged folks are running out of blood for em. As soon as I get done mowing/fixing mowers, I am building about 50 bird houses and one big butt bat house, snork. Only thing I got to do with my MB is move it out of the way this week
Yeah I dont like those geese and never been around a swan, but around these parts if something like that gets after me and causes any trouble they are very likely to come down with a serious case of lead poisoning if you know what I mean...LOL!OH Man Map! I didn't think of that! At the end of our property, is a marsh that is the end of a large pond or very small lake. Thank you! Like spammers, kill em young and be bothered less.
Ya got me thinking 20 or 30 feeder gold fish. Them things could survive a nuc war. The fish go quick here. Lots of geese and swan. (Or as i like to call em, large killer ducks.) They will chase a large dawg or a very kind Carol. They run from me. I go for their necks. LOL, freaks em out. Har, lol. Think I sould get an air horn.
Just realized my 3rd and doner parts mower has a really cool gas tank. Want to do a pusher MB and would work great.
